Histopathological examination revealed this cast to be composed of layers of cellular debris, accompanied by an infiltration of leucocytes. There was a mycotic infection most likely with candida. The diverticulum of the sac demonstrated squamous metaplasia of the epithelium and mild inflammation. The responsibility of keratinized cells and mycotic infection in the pathogenesis of dacryolith is discussed.
